[SOLVED] USB OTG is no longer working on my galaxy s8

I posted in this thread 8 months ago, right after I got the S8+, and I see the post was quoted a couple times. I should've posted back a few days after that, when I realized what was going on , but I'll do so now, just to set the record straight.

The problem wasn't with the phone — it was the fact I wasn't technically unfamiliar with the USB C-Type connector the phone comes with.

What I didn't realize was ᎓

OTG is already built into your phone's ( and every ) USB C-Type connector, because OTG is defined as part of the USB-C spec.

That means you don't need to ( and shouldn't ) plug any type of OTG cable or OTG adapter in there. If you do  try to include an OTG cable (one without a USB C-Type connector at either end ) in the connection, as some of us were doing ( present company included ), you definitely will  have problems.*  To get a USB storage device to connect and work with any phone which has a USB C-Type connector — like the S8, S9, and their "plus" variants — all you need is a single cable that has a USB-C male connector on one end ( which will plug into your phone ) and on the other end you want whichever type of USB connector fits the storage device you're trying to connect to your phone.

So for example if it's a USB 3.0/3.1 stick or flash drive you want to connect, the other end of the cable would be a female USB 3.0/3.1 A-Type ( full width ) connector. If it's a high capacity USB 3.0/3.1 portable drive you want to connect, as was my case, the other end of the cable would be a male USB 3.0/3.1 Micro B-Type ( the one that looks "split" in the middle ). Soon as I bought a cable like that and made it the sole connection between my phone and portable drive, all problems disappeared and I could read the drive from the phone without issue.

Point is, if you have a phone with a USB C-Type connector, OTG is no longer a concern to you, and you no longer need for special OTG cables ( or adapters, or anything ) to be part of the connection chain, because OTG logic is built right into USB C-Type connectors and cables. At first I thought USB C-Type was just yet another differently-shaped USB connector, one that was reversible, but really it's a key upgrade to the USB spec, one with "smart" connectors and fully-featured cables that are both reversible and OTG-ready. And it's going to be around for awhile, so buying a couple of USB C-Type cables to interface your storage devices with your phone isn't money wasted.

- -
* At that point the proper procedure is (a) post about how much you hate your new phone because OTG doesn't work, (b) quietly figure it out at some later point ("oh … heh-heh"), and (c) update that post several months later explaining how much of a dork you were back then, which most everyone who read your first post already knows.

Otg connection

I am running SM-G950F with ALEXIS 5.3, rooted with Magisk, and I had the same problem...
until I plugged the Samsung OTG adapter which goes from USB C type to USB B type.
When you plug this into the S8 port and then connect a USB stick into it, the S8 will read the stick

Did anyone go forward with that? I have the same problem. OTG Cable works perfectly on my friends non-galaxy phone.
Connection with computer works fine. Charging works fine too. , but ignores any OTG connection.
I dont know exactly what was the turning point for WORKING to NOT WORKING, but it worked months ago. Then, recently I needed OTG function and saw that something has happened and it totally ignores any OTG connection. Meanwhile USB connector got wet and I updated firmware.
Did anyone have the solution for it? As I still have my Samsung warranty, I am trying to avoid rooting it.
Can anyone help?

The way it worked for me: Connected the thumb-drive to another phone with USB-C (Google Pixel 2 in my case), formatted the thumb and plug it in Samsung S9+. All good :) I know it requires another phone but it was the only solution i found.

The otg on my s8 is not working So it all started when i brough a new ledger nano s and when i tried to use the otg cable it diddent work so i tried a usb stick and that diddent work ..ive got 2 otg conectors one of wich came with the device and ive tried connecting multiple things to my s8 and nothing works no notifications nothing apsloutley nothing like i haddent even plugged aneything in but after some playing about (this only happend once) when i was fiddling about with it the light on the usb momentarily flashed once and thats all i got ..so i know theres power there somewhere .... now i know what your going to say ... the cable is crap and the the charging port is loose but ive just been and purchesd a new otg adapter ..still not working ..and only 3 weeks agow i had a new chassie and screen put on my s8 along with a new charging port so unless he screwd me on that i dont know ...but one last thing is the s8 in question was previousley rooted and after i had a new screen put on it i unrooted it by reinstalling the stock firmware from sammobile chould this be a cause
